Hi,

create table dbo.MyTable
(id int,
name varchar(20)
)

insert into dbo.MyTable(id,name)
values(0, 'John')

The following works (gives me 0):

declare @TableName varchar(20), @SomeInt as int
set @TableName = 'dbo.MyTable'

declare @SQL varchar(1000)
set @SQL = 'SELECT count(*) FROM ' + @TableName
 exec(@SQL)

But this doesn't work:

declare @TableName varchar(20), @SomeInt as int
set @TableName = 'dbo.GunniTemp'

declare @SQL varchar(1000)
set @SQL = 'SELECT count(*) FROM ' + @TableName
 exec(@SQL)
set @SomeInt = exec(@SQL)

Anybody know why?

Thank you
